VJOSEPI-I I. BUNNQor WASHINGTON, nrs'rnicr or COLUMBIA? HEATING nnvron non eAs' STOVES'AND 'nANeEs;

To all whom it may concern:

Be it known that I, JOSEPH T. BUNN, a citizen of the United States, residing at lVashington, District of Columbia, have in vented certain new and useful Improvements in Heating Devices for Gas Stoves and Ranges, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a heating device for gas stoves and has forits principal object the production of a casing wh1ch may be placed upon a gas stove in a simple manner so as to allow the heat from the flamesto efliciently heat a plurality of 0011s whereby:

water may be heated, at which time the heat may be expelled from the casing for heating any vessel which may be carried by the outer portions of the casing. I

Another object of this invention is the production of a heating casing which may of coils whereby the heat from the flames may heat the coils the upper portion of the casing being adapted to rest upon the coils for efficiently retaining the same in their correct position, this upper portion being so formed as to allow heat to be expelled from the casing to allow the same to heat a vessel carried upon the outer portion thereof. 7

A still further object of this invention is the production of a heating device for gas stoves wherein the casing may be positioned so as to allow the burners of the stove to be positioned within the interior thereof in such manner as to cause the flames to heat the coils carried by the casing and allow the heat to be expelled from the casing as desired.

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the drawing :Figure 1 is a central longitudinal section through the heating device, showing the same carried by a gas stove. Fig.2 is a top plan view of the heating device, the cover or top thereof being removed. Fig. 3 is a central transverse section through the heating device. Fig. 4 is a central transverse section through a slightly modified form of the heating device, where in the burners of-the gas stove are carried within the casing. Fig. 5 is a side elevation Specification of Letters Patent. Patented Feb 15, 1916 Application filed October 13,1914. Serial No. 866,522.

of the modified form of the casing as shown in Fig. 4. Fig. 6 is a fragmentary perspective view of one of the barsand supporting standards therefor. Fig. 7 is a detail perspective view of one ofthe covers for the top. 7

Referring to the accompanying drawing by 'numerals, l designates in general a gas stove upon which this heating device is adapted to be positioned. This gas stove 1 1s provided with-the usual burners 2 for supplying heat to the casing for heating the coils thereof and also for heating a suitable vessel which may be carried thereby.

-The casing-3 comprises a box-like structure having. a supporting base '4 and side walls 5 terminating in lateral flanges 6 at formed as to register with the burners 2 for 1 allowing the heat to pass upwardly into the be-carried upon a gas stove and which is so formed as to efficiently support aplurality interior of the'heating device or casing.

' A plurality of burner standards 8 are carrled at spaced intervals within the side their upper portions. This base wall is pro-' 1 vided with enlarged openings 7 which are so r portions of the casing 3 and upon these.

standards 8 there iscarried a, plurality of supporting bars 9, as'clearly shown in Fig.

1. i These bars or standards are held in engagement with each other by means of the dove-tail construction shown at 10 in Fig.-

6, whereby one of the bars and two of the standards will form a substantial rigid structure. The coils 11 are positionedwithin the casing'so as to rest upon the bars 9, as clearl shown in Figs. 1 and 2, whereby the coils will be held at a spaced distance above the burners 2 of the stove 1. These coils are provided with an intake pipe 12 and anexhaust pipe'l3 communicatingwith the outer portions of the casing, whereby water may be passedthrough the coils and efficiently heated, and then exhausted there.

from. The top 14 is positioned upon the coils 11-, as clearly shown in Figs. 1 and 3, and in this manner the coils will be held firmly in'engagement with the bars9 and will be prevented from losing their correct shape. This top 14 is alsoprovided with openings 15 formed in registry with the openings 7 formed in the base 4. Therefore,

when the heat passes upwardly through the casing 3 it will be expelled through the openings 15. It will be seen that a vessel may be positioned upon the top 14' so as to cover or partially cover one of the openings 15 and the heat from. the casing will pass around the vessel so as toheat the same for cooking any suitable substance carried therein. There are also provided-the caps lfi having handles 17 extending therefrom and these aps are adapted to close either one or both of the openings 15 when it is so desired. It will be seen that the top l-i i'shel'd'firmly upon the upper portions of the coils '11 whereby the coils will be held in their correct positions upon the bars 9. Thistop is retained by means of the rods 22 which pass through the top and bottom'as clearly shown in Fig. 3. By referring to Figs. 4: and 5 it will be seen that the side walls 5 of the casing may be provided with holes 18 for the reception of the gas pipes 19 which carry the burners 20. In forming the device in:this manner the base 4 is detachableso as to allow'the walls 5- to-be passed down overthe burners and allow the pipesl9 to pass through the slots-l8. The base may then be placed in position and the retainingbolts 21 passed upwardly so as to engage thetopxl i-of the casingfor holding the top and bottom in. en ga'gement with theside walls 5. This' forin of a casing is provided with the usual standards and bars for supporting the coils whereby the water may be eiiicientlyheated, at which time the heat will pass upwardly through the openings formed in :the top portion of thecasing-for heating a suitable vessel. carried thereby.

What I claim is:

1. In a heating casing the co'mbinationof an inclosed rectangular body,isai d body comprising a base having side walls, said base provided withburner openingsin its lower portion, a plurality of standards carried by said body and fitting snugly against said side walls, horizontal supporting ba-rscaiw ried by said St'ZIIldRI'ClSyCOIl'S carried upon said supporting bars, said casing being adapted to receive heat from a stove through said burner openings whereby said coils will be heated, said casingprovided withra top having openings formed therein above the openings formed in 'said basewherebyrthe heat within said casing can only be expelled through the last-mentionedopenings thereby necessitatingthe passing of the heat around the coils.
